Abstract:

Products of anodic dissolution of uranium metal and the cathodic reduction of uranium(IV) ions in a molten eutectic mixture of lithium and potassium chlorides are studied at 450°C using x-ray absorption spectroscopy. It is shown that UCl 6 3- - ions form in the melt as a result of the metal's anodic dissolution, and the metal-ligand distance in the complex ion is 0.284 nm. No complex ions of another configuration are found to form. Cathodic reduction of the UCl 6 2- - ions also yields the UCl 6 3- - ions, with longer U-Cl bonds. © 2007 Pleiades Publishing, Ltd.
